3. SAFE INSTALLATION REQUIREMENTS

Installation or repairs made by unqualified persons can result

in hazards to you and others. Installation MUST conform with
local building codes or, in the absence of local codes, with the

ANSI Z223.1 and the National Electrical Code NFPA70-f 990 or
in Canada the National Standard CANiCGA B149-1 and CSA

C.22.1 - Canadian Electrical Code Part 1.

The information contained in this manual is intended for use
by a qualified service technician familiar with safety proce-

dures and equipped with the proper tools and test instru-
ments.

Failure to carefully read and follow all instructions in this

manual can result in furnace malfunction, property damage,
personal injury and/or death.

• DoNOT usethisfurnaceas aconstructionheater.

• Useonlythe Typeofgas approvedforthis furnace(SeeRatingPlate).

• DoNOT useopen flameto testfor gas leak.

• Sealsupplyand returnair ducts.

• Checkto seethat filtersareinstalledcorrectlyandarethepropertypeandsize.

NOTE:It isthepersonalresponsibilityandobligationofthecustomertocontacta qualified
installerto ensurethat theinstallationisadequateandconformsto governingcodesand

ordinances.

CAUTION

It is recommended that a qualified service technician check the heat
exchanger integrity every two (2) years, after the first four (4) years of
operation.

4. LOCATING THE UNIT

ACCESS PANELS
See FIGURE1forageneralviewofunitandlocationofaccesspanels.

Carbon monoxide poisoning hazard.

Do NOTinstalltheunit in alocationthatwillpermitdischargedairfromthecondenserto
recirculatetothe condenserinlet.

CAUTION

Do NOT operate unit in a corrosive atmosphere containing chlorine,
fluorine, or any other corrosive chemicals.

airinletopeningsMUSTnotbeobstructed(seeFIGURE1).In addition,localcodesMUST

beobserved.
NOTE:Units withbuiltinfilterracks( "C" Chassis48x 73 models),need a26" minimum

clearanceatfrontofunitforremovaloffilters.Seechartbelowif unitisgoingtobe placed
nearcombustibleconstructionormaterials.

While minimumclearancesare acceptablefor safetyreasons,they may notallowade-
quateair circulationaroundthe unitfor properoperationinthecoolingmode.Whenever

possible,itisdesirabletoallowadditionalclearance,especiallyaroundthecondenserinlet
anddischargeopenings.

INSTALLATION

NOTICE

Unit will NOT operate properly unless it is installed level front to rear
and side to side.

The slope MUST NOT be greater than 1/8" per foot (10mm per meter).
For side to side leveling, the drain side MUST always be lower.

Ground Level Installation

Groundlevel platformrequirements:

- The unitMUSTbe situatedtoprovidesafo accessforservicing.
Platformmay be madeof eitherconcreteor pressuretreatedwoodand MUSTbe

level andstrongenoughto supportunitweight.

Installin well-drainedarea,withtopsurface ofplatformabovegrade level.
Platformmust be highenoughto allowfor propercondensatetrapinstallationand

drainage.SeeFIGURE4 andassociatedtextfor moreinformationaboutconden-
satedrainage.

Rooftop Installation

HOISTING

NOTE:All accesspanelsMUST besecuredin placebeforehoisting.
Theunitshouldbe hoistedwithtwo liftingslings.Attachtheslingsto riggingshacklesthat

havebeen hookedthroughholesin the baserail.

DOWNFLOW CONVERSION

These unitsare adaptableto downflowuse. Toconvert to downflowuse,follow these
steps:

1. Removethe blockoffplatesfoundin the returnaircempartmentandthe supplyair
compartment.SeeFIGURE2.

NOTE:Blockoffplateinthesupplyaircempartmentonlycontainsonescrew.Ifreinstalling

6. GAS SUPPLY AND PIPING

NOTE:Becausethere aremanytypesofliquifiedpetroleum(LP)gases,thetermLPas
usedinthis manualrefersto propanegas. Ifyouintendto useanytypeofLP gas,proper
precautionsMUSTbeusedinthehandling,piping,and useofsuchgas.NOTE:In Cana-
da,installationsMUSTbe performedby licensedLPinstallers.

TheUL/CSARatingPlatelocatedonthesidepanelonthe unitcontainsthemodelnumber,
typeof gasand gas inputrating,and otherimportantinformation.

Fire and/or explosion hazard.

Make certain the unit is equipped to operate on the type of gas

available. Models designated as natural gas are to be used with
natural gas only. Models designated for use with liquefied pe-

troleum (LP) gas are shipped with orifices sized for commer-
cially pure propane gas. They MUST not be used with butane or

a mixture of butane and propane unless properly sized orifices
are installed by a licensed LP installer.

Failure to follow this warning can result in property damage,

personal injury, and/or death.
